To'cll it may concern:

3e 1t known that I, MAXIMILIANUTOGH, a citizen of theUnited States, anda resident of the city of New York, borough of Man-' hattan, State of New York, have invented certain newand useful Improvements inPaint-Removers, of which the following is an exact description.

, must be applied which do not run off quickly.

jI have now found that by the addition of naphthalene, which is ahydrocarbon in solid form, to organic solvents a liquid is obtainedwhich adheres firmly to the paint and varpre arations of this kindheretofore de- I can rocee as follows: One ga an ably.

nish and makes its removal easyand quick. The addition of this solidhydrocarbon distinguishes my paint remover from all other scri ed.Naphthalene serves two purposes in my paint remover. First it reventsthe solution from running off quickly and second: after evaporation ofthe solvent it is left on thetreated surface as a fine coating whichsoftens and dissolves the paint and varnish. The paint removers of theold art generally contain mostly benzol or its equivalents, which act assolvents for the paint and varnish, and wax and its equivalents, whichreventthe solution from running off easily. a hthalene combines thefunctions of both,

A though I have above described a few exam les by which my new aintremover may e obtained, I do not Wis to be under stood as excluding frommy claims equivalents for the ingredients, the apparatus, or theoperations employed in the process. It

is probable that substitutes may be em-' ployed without departing fromthe scope of the rocess intended to be secured hereby.

I aving now described my invention and in what manner the same is to beperformed, what I claim as new and desire to secure by Letters Patent,is:
